Patent CA-2366972-A1 (CA)
Title: Coupling for trailer
Inventor: STEVENS JAMES E
IPC: B60D1/52
Filed: 2002-01-09
Abstract: The coupling interconnects a trailer and a conventional hand-held two-wheeled cart. The coupling includes a frame to which a ball of a ball and socket joint is connected. The frame has a recess which is adapted to removably receive the forward portion of a lower plate of the cart. The coupling is connected to the cart by inserting the forward portion into the recess. The coupling is then positioned such that its ball is beneath the socket on the hitch of the trailer. When the cart is tipped backward, the ball rises and enters the socket and lifts the hitch thereby permitting the trailer to be moved by the cart.

Patent CA-2370964-A1 (CA)
Inventor: DOWNS WILLIAM
IPC: F23G5/027
Filed: 2000-04-21
Abstract: A method and apparatus for processing a waste stream from digestion of lignocellulosic material to form useful products. The waste stream (1) can comprise black liquor, red liquor, alkaline, acidic or neutral sulfite spent  liquor, or polysulfide spent liquor. Partial oxidation (100) is performed on  the waste stream to form hot gases and molten salts. These are cooled using a quench liquor (102) to form quenched gas and carbonate liquor from which particles are removed to form a raw fuel gas. H2S is removed from the raw fu el gas using an H2S removal process (105) which is more selective for H2S than it is for CO2, following the particle removing step (104), thereby forming usab le fuel gas (5) as one useful product, and acid gases (6). Further processing i s performed on the acid gases to produce additional useful products.

Title: Loop antenna with at least two resonant frequencies
Inventor: LEISTEN OLIVER PAUL
IPC: H01Q5/10
Filed: 2000-05-24
Abstract: A dielectrically-loaded antenna for operation at frequencies in excess of 200 MHz includes an antenna element structure disposed on a high dielectric constant core, which element structure comprises a pair of laterally opposed groups of helical antenna elements. Each group comprises first and second mutually adjacent elements, of different widths providing looped conductive paths on the antenna, formed by the first elements of each group and the second elements of each group respectively, which resonate at differing respective resonant frequencies to yield a relatively wide operating bandwidth.  The helical elements of each group define, between them, part of an elongate channel which has an overall electrical length in the region of n.lambda./2 within the operating frequency band to provide isolation between the looped conductive paths. The major part of each such channel is located between the elements so as to minimise intrusion into other conducting parts of the antenna.

Abstract: Methods for the production of purified, catalytically active, recombinant memapsin (2) have been developed. The substrate and subsite specificity of t he catalytically active enzyme have been determined. The substrate and subsite specificity information was used to design substrate analogs of the natural memapsin (2) substrate that can inhibit the function of memapsin (2). The substrate analogs are based on peptide sequences, shown to be related to the  natural peptide substrates for memapsin (2). The substrate analogs contain a t least one analog of an amide bond which is not capable of being cleaved by memapsin (2). Processes for the synthesis of two substrate analogues includi ng isosteres at the sites of the critical amino acid residues were developed an d the substrate analogues, OMR99-1 and OM99-2, were synthesized. OM99-2 is bas ed on an octapeptide Glu-Val-Asn-Leu-Ala-Ala-Glu-Phe (SEQ ID NO:28) with the Le u- Ala peptide bond substituted by a transition-state isostere hydroxyethylene group (Fig. 1). The inhibition constant of OM99-2 is 1.6 x 109 M against recombinant pro-memapsin 2. Crystallography of memapsin 2 bound to this inhibitor was used to determine the three dimensional structure of the protein, as well as the importance of the various residues in binding. This information can beused by those skilled in the art to design new inhibitors,  using commercially available software programs and techniques familiar to those in organic chemistry and enzymology, to design new inhibitors to memapsin (2), useful in diagnostics and for the treatment and/or prevention of Alzheimer's disease.

Filed: 2000-06-09
Abstract: La présente invention concerne des enzymes recombinées produites à partir de levures transformées avec des gènes codant pour des protéinases d'acide aspartique d'origine végétale. Ces protéinases présentent une activité de coagulation du lait de brebis, de vache et de chèvre considérable. Elles peuvent être produites en grandes quantités par la culture de levure transformée dans un milieu liquide. Elles sont sécrétées dans le milieu de culture et peuvent être disponibles sous forme liquide ou lyophilisée. L'activité des enzymes est similaire à celle de la chymosine (enzyme d'origine animale) utilisée pour la production de fromage à l'échelle industrielle. Les protéinases d'acide aspartique recombinées se différencient de la chymosine par leur capacité de clivage de la caséine. Les enzymes d'origine végétale recombinées sont à l'origine du clivage des caséines .alpha., .beta. et ~, alors que la chymosine est uniquement à l'origine du clivage de la caséine ~. L'aptitude au clivage des caséines .alpha., .beta. et ~ des protéinases d'acide aspartique recombinée d'origine végétale permet de produire un fromage ayant une saveur, une odeur et une consistance particulières.

Abstract: L'invention concerne un procédé permettant de déterminer la dureté d'un produit, par exemple un fruit. Ledit procédé consiste, lors du cycle de mesure, à soutenir le produit et le à tapoter à l'aide d'un dispositif de frappe sur au moins une de ses positions. Ainsi mis tout entier en vibration naturelle, ledit produit émet des signaux de vibration. Lesdits signaux, captés à l'aide d'un capteur, sont traités à l'aide d'un dispositif de traitement de signaux pour déterminer la dureté FRi du produit. Le procédé consiste en outre à détecter les signaux émis par le dispositif de frappe à l'aide d'un second capteur de signaux; à traiter les signaux de vibration à l'aide d'un second dispositif de traitement de signaux. Les propriétés élastiques du produit sont déterminées  dans une zone de volume au-dessus de ladite position précitée; à déterminer la dureté FIi du produit; à comparer FIi et FRi et à vérifier la comparaison avec une valeur préréglée. Le tapotage et la détection à l'aide du second capteur de signaux seront répétés dans le cas où la comparaison ne correspond pas à la valeur préréglée. On peut ainsi déterminer avantageusement la dureté, en particulier pour ce qui concerne l'étiquetage des produits lors du choix et du tri des fruits. On peut utiliser un dispositif pour réaliser ce procédé dans des applications de bureau et des déterminations en ligne sur des machines à trier.
